[OctDev] print.m no longer working

[Michael C. <mic...@ua...>]

Hello all,
I'm trying to use print to create some .eps files. It's no longer working:

octave:1> plot(rand(3,1))
octave:2> print("test.eps","-depsc2")
warning: in fopen near line 55, column 3:
warning: fopen: default open mode is now binary
error: plot: can only plot in 2 or 3 dimensions
error: plot: can only plot in 2 or 3 dimensions
error: called from `print' in file 
`/usr/share/octave/2.1.69/site/m/octave-forge/plot/print.m'

I guess that print.m needs some updating, if anyone knows what needs to be 
done.
Thanks, M.           

[OctDev] strtok vs column arrays

[Tom H. <to...@ku...>]

fread with 'char' returns a column array; eventually this got passed 
to strtok.  In strtok, there's a
	skip = find(idx != 1:length(idx))
which failed because 1) there were multiple instances of the 
delimiter, and 2) idx is a column and the : is a row.
For example, in matlab:
 >> s = 'abca';
 >> strtok(s, 'a')

ans =

bc

 >> strtok(s', 'a')

ans =

b
c

In octave:
octave:1> s = 'abca';
octave:2> strtok(s, 'a')
ans = bc
octave:3> strtok(s', 'a')
error: mx_el_ne: nonconformant arguments (op1 is 2x1, op2 is 1x2)

One way to fix this is:
--- #strtok.m   2005-05-15 16:18:02.000000000 -0400
+++ strtok.m    2005-05-15 16:47:53.000000000 -0400
@@ -57,6 +57,7 @@
        tok = str;
        rem = "";
      else
+      idx = reshape(idx, [1 length(idx)]);
        skip = find(idx != 1:length(idx)); # find first non-leading 
delimiter
        if isempty(skip)
         tok = str(idx(length(idx))+1:length(str));

Try running ldd on octave. What blas/lapack libraries is it lnked to? I 
have a hunch that it is linking to a P4 version of ATLAS and you have an 
AMD or a P3, that doesn't implement SSE2....

hi folks
perhaps no quite the right list, but I'm using octave 2.1 in debian
sid, and i'm getting the following error whe I try to invert a matrix

octave:1> inv([4 2; 7 6])
panic: Illegal instruction -- stopping myself...
attempting to save variables to `octave-core'...

Illegal instruction

any ideas? :(

[OctDev] conftest.cc has problems with tetex-3.0

[R S A. M. <rsa...@sa...>]

Hello:

I am trying to build octave-forge-2004.11.16 on Slackware 10.1. I have 
found that ./configure recognizes all required libraries properly only 
when I have tetex-2.0.2 installed on the system. I removed tetex-2.0.2 
and installed tetex-3.0 which is the latest version. After this, if I 
try ./configure, it is giving several error messages. How to correct 
this? Can we not make ./configure work with tetex-3.0?

Thanks for your help.

Re: [OctDev] setfields.m seems to tests for nargin incorrectly

[Andy A. <ad...@nc...>]

I've made a change to the CVS to support this. Note,
however, that s= struct() only works in newer versions
of octave (works in 2.9.2 and not in 2.1.42 - I don't
have others lying around to test)

setfields now reads:

    function s = setfields(s,varargin)
    if nargin == 0
      s= struct; % doesn't work on older versions of octave
    elseif rem(nargin,2) != 1,
      error('setfields: expected struct, key1, val1, key2, val2, ...\n') ; 
    endif
            
    for i=1:2:nargin-1
      if ! isstr(varargin{i}) ,
        error('setfields: called with non-string key') ; 
      else
        eval( ['s.',varargin{i},'=varargin{i+1};'] ) ;
        end
      end
    end

I encountered this because optimset.m has the line 45:

which caused the original setfields.m:

function s = setfields(s,varargin)

      error('setfields: called with odd number of arguments\n') ;

to complain.
nargin==0 should be a valid call to setfields, so maybe some easy fix
would be:

function s = setfields(s,varargin)
if nargin>0
  if rem(nargin,2) != 1,
        error('setfields: called with even number of arguments\n') ;

Note that this is just a documentation bug. The first

[OctDev] Re: isdir.m

Hmm.  I posted isdir.m, because I couldn't find it on the octave-forge 
webpage.  Turns out, isdir is in there, but it doesn't show up under 
"I" here: http://octave.sourceforge.net/index/index.html.

[OctDev] fzero.m doesn't pass varargin to feval

[Ben B. <bar...@al...>]

fzero doesn't seem to pass varargin to feval. There are 6 places=20
including the function statement itself where varargin (function=20
statement) or varargin{:} (when using feval) is needed. I have tested=20
this modified fzero.m for varargin functionality and include it below.

[OctDev] setfields.m seems to tests for nargin incorrectly

[Ben B. <bar...@al...>]

In setfields.m, the nargin check seems to be incorrect:
if rem(nargin,2) != 1,
       error('setfields: called with odd number of arguments\n') ;
endif

Seems like the 1 should be a 0, or equivalently != should be == .

Hello:

I removed the latest tetex-3.0 package and reinstalled tetex-2.0.2 which 
comes with Slackware 10.1. After this, when I run ./configure 
--prefix=/usr --build=i486-slackware-linux, it recognized all the 
libraries properly in the end. So, I suspect something wrong with the 
latest package. What could it be? The log file when I configured with 
tetex-2.0.2 is attached.

[OctDev] Configure recognizes libpng, libjpeg, gsl and qhull and their header files initially but still reports not found in the end.

[R S A. M. <rsa...@sa...>]

Hello:

I am trying to compile octave-forge-2004.11.16 on a Slackware 10.1
system. I have installed cln, ginac, libpng, libjpeg, gsl, qhull along 
with their corresponding header files. But when I run
./configure --prefix=/usr --build=i486-slackware-linux
it recognizes only ginac in the end.

I have attached config.log file. As we can see from this, all the 
library files mentioned above and their header files are recognized 
earlier but still configure reports libpng, libjpeg, gsl and qhull not 
found in the end! What is the problem?

Can anybody help? Thanks for your help.

Have you installed the development packages? I'm not familiar with 
Slackware, but many other distributions create two packages for 
libraries such as those you listed. In Fedora, for example, while libpng 
could be installed, configure is looking for header files that are found 
in a separate package called libpng-devel. If you have everything 
installed, I'm not sure what the problem is.

I have libjpeg and libpng both installed. But still configure is 
reporting that they are not present. What is the mistake? Can anybody help?

Thanks for your help.

I have here:

$ octave-config --version
2.1.69
$ echo "which griddata" | octave -q -f
griddata is the user-defined function from the file
/usr/share/octave/site/m/octave-forge/geometry/griddata.m

Yes, it seems to be a bug.  Unfortunately, I am not very used to the
octave-forge configure/Makefile scheme and I would prefer that someone
else review this issue.

I noticed that "make install" in octave-forge would install
delaunay.m (and related) even though qhull is not present and
delaunayn.oct has not being built.
Perhaps this is a bug in the octave-forge configure script?

Sincerely,
Dmitri.
